甲基膦酸二异戊酯(DAMP)是一种应用于铀化合物纯化工艺的中性磷型萃取剂,它对铀的萃取性能较常用的磷酸三丁酯(TBP)优良。由于DAMP分子中具有一个稳定性较高的C—P键,它的化学及辐照稳定性也应高于TBP。索洛夫金(Соловкин)等曾对甲基膦酸二异戊酯的萃取性能进行了一些基本的研究。但它的制备方法文献上还缺乏详细记载。本文报导这个萃取剂的几种合成方法。
Diamyl methylphosphonate (DAMP) is a neutral phosphorus extractant used in the purification of uranium compounds. It is superior to TBP which is more commonly used in the extraction of uranium. Due to the DAMP molecule has a higher stability of the C-P bond, its chemical and radiation stability should be higher than TBP. Solofjin (Соловкин) and so had on the extraction of methyl isobutyl methyl phosphonate performance of some basic research. However, its preparation method is still lack of detailed documentation. This article reports several ways to synthesize this extractant.
